WHEELWRIGHTS GAGE.

SPECIFICATION forming part of Letters Patent No. 242,457, dated June 7,1881.

Application filed April 8, 1881.

T 0 all whom it may concern Be it known that I, HENRY KAPPNER, ofDenver, in the county of Arapahoe and State of Colorado, have inventedcertain new and useful Improvements in VVheelwrights Gages; and I dohereby declare that the following is a full, clear, and exactdescription of my invention,which will enable others skilled in the artto which it appertains to make and use the same, reference being had tothe accompanying drawings, which form a part of this specification.

This invention relates to that class of devices commonly known aswheelwrights gages; and it consists in the combination and constructionof parts, ashereinat'ter fully described, and particularly pointed outin the claims.

In the drawings, Figure l is a side elevation; Fig. 2, a top or planview; Fig. 3, a section taken through the same on the dotted line .70 m.Fig. 4 is a detail view, and Fig. 5 is a transverse sectional view ofthe bar 0 and plate E on the line y y.

A indicates a bar provided with a semicircular slot, B, in its enlargedend A.

(J is a bar provided with slots D D and with a plate, E, which issecured by screws, so that it can be detached when the device is usedfor light work. The bar 0 is connected with the bar A by means of alink, F, that is pivoted to the bar A, and provided with a pin, j, whichpasses through the lower slot, D,of the bar 0.

G indicates a long metal yoke or link,-having at one end a pin, g, whichpasses through the upper one of the slots D in said bar (J. The sidebars of this link G pass through the sleeves H H, and are formed withslots I I, through which passes the pin K, that pivots these sleevesupon opposite sides of the enlargement A of the bar A.

L indicates another yoke or link, which embraces the link G, the sidebars of said yoke L also passing through the sleeves H, and being eachprovided with a perforation,through which the pin K passes.

The sleeves H have each a flange or ear, M, through which passes aset-screw, N, said setscrew also passing through the slot B in theenlargement A of the bar A. A set-screw, 45, passes through the outerend, I, of the yoke or (No model.)

A notched plate, O, is arranged within the link Br, and the set-screwialso passes through this plate.

The bar A, in addition to the enlargement A at its upper end, is alsoprovided at said end with a head or plate, A having an opening, A madethrough it, so that the sides of said opening are formed of the bar Aand the three bars a a a, the bar a being at an ob tuse angle to the barA, the bar a at a right angle to the said bar A, and the bar a whichconnects the ends of the bars a a, being curved;

P indicates a roller, which rests upon the upper side of the bar a so asto travel along the same. This roller is mounted upon a link, Q, whichconnects with the upper end of the bar 0, so as to suspend said bar.

R indicates a wooden bar, which is pivoted to the upper end of bar A,said bar B being bifurcated at its pivoted end, and its prongs beingadapted to embrace the head A of the bar A. A set-screw, 1", passesthrough the bifurcated end of the bar R, and also through metal plates1", that are secured to said bar.

The bar A is provided with a series of holes, 1*, for the reception of ascrew-threaded pin, S. The bar R is provided with a clip, T, adjustablysecured thereto by a set-screw, t. A long rod or pin, U,passes throughthis clip, and can be adjusted up or down through the same.

In using this device it is manipulated as follows The bars A O areinserted into the axlebox up to the screw-pin S, which can be secured inthe required hole provided for its reception. The bar 0 is moved awayfrom the bar A to fill the box by moving the link L upon its pivot,which will consequently vibrate the link G connecting with the upperslotted end of bar 0, and which will also vibrate the link F by reasonof the connection that is made between the links F and G by means ofrods V V. The two bars will be then held apart by tighteningup setscrewN, that passes through the ears of sleeves H, so as to clamp said earsupon the enlargement A of bar A. In order to now adjust the bars to thebevel of the box, the set-screw i, that passes through the links L G, isoperated, the said link G mov link L. and also through the outer end, 9of the link G, which is within the yoke L.

ing within the link L, since the pin which pivots the outer link passesthrough slots in the inner link, and hence, as the inner link, G,connects with bar 0, the upper end of said bar will be moved toward oraway from bar A, according to the direction in which the setscrew isturned. It will be noticed that the roller upon thelink connecting withthe upper end of bar 0 admits of such movement of the bar.

The bar R can be moved up or down, as may be required, and secured atthe desired an gle by tightening up the set-screw that passes throughits bifurcated end, the prongs being either clamped upon the head of barA; or, if desired, the plates 1" may be spring'plates and have pins attheirends adapted to pass through bar R and bear against the curved bara of the head of bar A when said set-screw is tightened up.

The pin U will be adjusted by the operator with reference to therequired gage, and the clip throughwhich the pin passes can be adjustedupon the bar with reference to the diameter of the wheel.

The above-described device is especially applicable for gaging the dishof. wheels, as will be readily understood by those skilled in the art.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination, in a wheel wrights gage,

of the bar A, having a semicircular slot at one end, with the bar 0,provided with two slots, the link F, connecting said bars, a link, Gr,connected by rods with the link F, and the link L, connected with thebars A and O, substantially as described.

2. In a wheelwrights gage, the combination of the bars A G, connected bylinks, the roller arranged in the opening of the head of bar A, andmounted upon a link connecting with the bar 0, the set-screw bar,adjusting-links G- L, and the pivoted arm It, carrying an adjustableclip and pin, as set forth.

3. The combination of the bars A 0, connect ng-Iinks F G Ii, rods V, andthe sleeves H II, having lugs M and set-screw N, all arranged andoperating as herein-described, for the purpose set forth.

I. In awhcelwrights gage constructed sub stantially as described, thecombination, with the bar A, having semicircular slot 1- and theadjustable bar 0, of the pivoted sleeves H H, having lugs M and setscrewN, sliding link (I, connected adj ustably to the bar (I, and the pivotedlink L, substantially as herein described, for the purpose set forth.

In testimony that I claim the foregoing as my own [have hereto aflixedmy signature in presence of two witnesses.
